This afternoon - 2 p.m. - I'll be covering the arraignment of Ernest Wallace on a murder charge stemming from the June 2013 homicide of Odin Lloyd in North Attleborough.

Wallace, 45, was previously charged with accessory to murder after the fact and is being held on $500,000 cash bail.

Prosecutors are expected today to explain the basis for charging Wallace with murder.

Local legal analysts have said the new charge indicates that the Bristol County District Attorney's Office may be pursuing a joint venture theory that Wallace, former Patriots star tight end Aaron Hernandez and Carlos Ortiz, 27, conspired to murder Lloyd, 27, in the North Attleborough Industrial Park.

Ortiz - who was previously charged with murder to accessory after the fact - was also indicted for murder, and he is scheduled to be arraigned on that new charge on May 27 in Fall River Superior Court.

Meanwhile, there was major breaking news this morning out of Boston regarding Hernandez's alleged role in a double homicide in the South End of Boston on July 16, 2012.

The Suffolk County District Attorney's Office announced two murder indictments that allege Hernandez shot and killed two men, and wounded a third individual, after pulling up alongside their vehicle in his SUV.

Prosecutors said Hernandez fired at the men with a .38-caliber revolver, which has been recovered by an associate of Hernandez.

The shooting happened after a "chance encounter" between the victims - Daniel de Abreu and Safiro Furtado - and Hernandez at a nightclub, Suffolk County District Attorney Dan Conley said during a press conference this morning.

Conley said that de Abreu and Furtado, contrary to earlier media reports, were not connected to Cape Verdean gangs in Dorchester, and that neither were involved in criminal activity.

Conley said the victims were 'ambushed and executed' by Hernandez, who is expected to be arraigned on the new murder charges next week in Suffolk County Superior Court.

If the allegations are true, that means Hernandez played the entire 2012 NFL season with the Patriots after having killed two men in a drive-by shooting.

Legal analysts said to expect prosecutors in Suffolk and Bristol counties to try to introduce evidence from both cases to their respective juries if they can argue that the two cases are somehow related. It has been reported that Lloyd may have known about Hernandez's alleged role in the double homicide, and that he may have been talking about it too widely.

Either way, expect Hernandez's lawyers to fight tooth and nail to prevent evidence from one murder case being introduced into the other one.
